Hyundai Sonata Transmission Fluid

Which transmission fluid the Hyundai Sonata uses by model year and transmission, and how to check the level.

Quick answer

SP-IV (2011 6-speed, including hybrid); SP4-M ATF (2020–2022 8-speed); GL-4 SAE 70W (2015 1.6T dry dual-clutch); WDH0-1 and WDG0-1 (2021 N Line wet dual-clutch) — confirm for your year and transmission. Dipstick: Not confirmed for every year — see your owner's manual. Hyundai's service bulletins check the 2011 6-speed and 2020–2022 8-speed through a level plug. Fill capacity and change interval depend on your exact year, engine and transmission, so they are not listed here — use your owner's manual.

Confirm your exact version. The Hyundai Sonata was sold across several model years and more than one transmission. What is shown here is general guidance and has not been verified for every individual configuration. Before buying fluid or servicing, confirm the fluid spec, capacity, and check procedure for your exact model year and transmission using the owner's manual or a dealer parts lookup for your VIN.

This is general guidance for the Hyundai Sonata. Always confirm the exact fluid spec and capacity for your model year in the owner's manual before servicing. Official source: Hyundai owner's manuals.

How to check it

Check the transmission fluid section of your Hyundai Sonata owner's manual first — it says whether your version has a dipstick, is checked at a fill/level plug at a set temperature, or should be checked by a dealer. See our step-by-step guides:

Frequently asked questions

What type of transmission fluid does the Hyundai Sonata use?+

For the Hyundai Sonata: SP-IV (2011 6-speed, including hybrid); SP4-M ATF (2020–2022 8-speed); GL-4 SAE 70W (2015 1.6T dry dual-clutch); WDH0-1 and WDG0-1 (2021 N Line wet dual-clutch) — confirm for your year and transmission. Always confirm the exact specification for your model year in the owner's manual before topping up or changing fluid — using the wrong fluid can damage the transmission.

Does the Hyundai Sonata have a transmission dipstick?+

We have not confirmed this for every Hyundai Sonata model year. The official documents we checked are listed on this page; your owner's manual's transmission fluid section says whether your version has a dipstick or should be checked by a dealer.

How often should Hyundai Sonata transmission fluid be changed?+

The interval depends on your model year, transmission and how the vehicle is used, so we do not publish a single number for the Hyundai Sonata. Your owner's manual or maintenance schedule gives the interval, usually with a shorter one for severe service such as towing, extreme heat or stop-and-go driving.
